Histogram: a graphical display of data using bars of different heights.

It is similar to a Bar Chart, but a histogram groups numbers into ranges .

The height of each bar shows how many fall into each range.

And you decide what ranges to use!

Example: Height of Orange Trees

You measure the height of every tree in the orchard in centimeters (cm)

The heights vary from 100 cm to 340 cm

You decide to put the results into groups of 50 cm:

So a tree that is 260 cm tall is added to the "250-300" range.

And here is the result:

You can see (for example) that there are 30 trees from 150 cm to just below 200 cm tall

(PS: you can create graphs like that using Make your own Histogram)

Notice that the horizontal axis is continuous like a number line:

Example: How much is that puppy growing?

Each month you measure how much weight your pup has gained and get these results:

0.5, 0.5, 0.3, −0.2, 1.6, 0, 0.1, 0.1, 0.6, 0.4

They vary from −0.2 (the pup lost weight that month) to 1.6

Put in order from lowest to highest weight gain:
−0.2, 0, 0.1, 0.1, 0.3, 0.4, 0.5, 0.5, 0.6, 1.6
You decide to put the results into groups of 0.5:

And here is the result:

(There are no values from 1 to just below 1.5, but we still show the space.)

The range of each bar is also called the Class Interval

In the example above each class interval is 0.5

Histograms are a great way to show results of continuous data, such as:

But when the data is in categories (such as Country or Favorite Movie), we should use a Bar Chart.

Frequency Histogram

A Frequency Histogram is a special graph that uses vertical columns to show frequencies (how many times each score occurs):

Here I have added up how often 1 occurs (2 times),
how often 2 occurs (5 times), etc,
and shown them as a histogram.

An outlier is an unusually large or small observation. Outliers can have a disproportionate effect on statistical results, such as the mean, which can result in misleading interpretations. For example, a data set includes the values: 1, 2, 3, and 34.

Distribution Systems Defined

Distribution systems can be defined as the sequential flow of procedures, systems, and activities which are designed and linked to facilitate and monitor the movement of goods and services from the source to the consumer. Essentially, distribution is about making products and services available to the end users when and where they need them.

Often times, you might hear the term channel of distribution or a marketing channel in reference to the distribution systems. These two terms relate to a group of organizations or individuals who have an impact on the flow of products and services from the source production and the end consumer.

To reiterate, distribution systems refer to making products and services available to the customer base when they are in need and where they can be used. Below are some of the key attributes associated with distribution systems and the benefits they offer:

Time: when the consumer wants to obtain the product or service.

Place: the place attribute is where the consumer wants to obtain the product or service.

Control: consumer ownership of the product or service.

Method: the specifics to the distribution channel; ex. a private label grocery product being manufactured by different producers.

Critical to the design of the distribution system, each attribute has a role and responsibility in the end-to-end system and shares common goals, such as profit and growth, which are attained with a unified process.

Types of Distribution Systems

Within a distribution system we can find multiple channels to enable distribution. The following list and examples will provide some insight to some of the common channels we see around us.

An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst (or a consensus process) to decide what will be considered abnormal.

In marketing, goods can be distributed using two maintypes of channels: direct distribution channels and indirect distribution channels. Direct Distribution. Adistribution system is said to be direct when the product or service leaves the producer and goes directly to the customer with no middlemen involved.

What is a Dot Plot?

As a school teacher, Mr. Page likes to have snacks available to reward his students for good behavior. He took a poll on the first day of school to find out what kinds of snacks the students prefer. This table shows the results for one of his classes:

While the table was an efficient way to display the data, Mr. Page wanted to present it in a more visual format, so he decided to create a dot plot.

A dot plot is a graphical display used in statistics that uses dots to represent data. Dot plots can be used for univariate data; that is, data with only one variable that is being measured. Dot plots are useful when the variable is categorical or quantitative. Categorical variables are variables that can be organized into categories, like types of sports, ice cream flavors, and days of the week. Quantitative variables, on the other hand, are variables that can be measured and have numerical values. Population, shoe size, and heart rate are examples of quantitative variables.

Dot plots work very well for data with a small number of values. They would not work well for large sets of data, because a dot would need to be plotted for each value. Histograms or box plots are more useful for large sets of data.

Creating a Dot Plot

To create a dot plot, we start by drawing a horizontal line with categories or numbers written beneath it. For the preferred snack results, Mr. Page wrote the names of each snack under the line. Then, he drew a dot above the line for each student who chose that particular snack. For example, he drew eight dots above popcorn, four dots above pretzels, five dots above M&M's, and so on. The numbers represent the frequency of each result, or how often the result occurs. Each dot represents one student, so the total number of dots is equal to the total number of students. In this example, there are 26 dots representing the snack choices for the 26 students.

Using Dot Plots

The students in Mr. Page's class enjoyed seeing the results of the snack survey displayed on the board, so he decided to create another dot plot, showing the number of siblings for each student. His class was able to identify some interesting information, such as the range, shape, and mode of the data.
